JOHN ARNE RIISE has been involved in a bust-up that has led to the dismissal of his international team mate, John Carew from the Norwegian training camp.

As the Norwegian players prepared for tomorrow night's friendly with Portugal, it is thought Riise (pictured) and Carew became involved in an argument concerning Riise's passing which eventually flared up and resulted in Carew punching the Liverpool midfielder in the face.

Two local papers in Norway, VG and Dagbladet, have reported Riise and Carew - who was recently linked with a loan move to Everton before leaving Valencia to join Roma - as arguing heavily throughout yesterday's training session before being separated by Wolves Striker Steffen Iversen.

The clash, which occurred on the team bus, left Norway coach Nils Johan Semb with no option but to send Carew home.

When asked about the incident at a news conference this morning, Semb confirmed: "Carew hit Riise."

He added: "John has been taken out of training and of the squad. He has chosen himself to travel to Rome."

Semb described the incident as "unacceptable behaviour" but said that Carew had apologised to the other players.

Liverpool midfielder Riise said: "He (Carew) has apologised for what he did and I apologised for what I did. We shook hands afterwards."
